Hello @ssaurabhhibernate,
As I already stated there:
Please […] provide more information, in particular the mapping you are using. If you mapping is complex, it would help to provide a reproducer based on our test case templates.
We really need your mapping to diagnose potential performance issues, otherwise we might as well give you random answers.
I noticed you are also having trouble with performance with Hibernate ORM. I would advise you to solve those performance issues first, as a non-optimized ORM mapping will perform poorly both in ORM and in Search.
